1. A joint implant device, comprising:
a cylindrical anchor with a central longitudinal axis, the cylindrical anchor including:
a distal portion that comes to a point, the distal portion configured to be inserted into cancellous bone adjacent to a joint;
a proximal portion with a flat top end, the proximal portion comprising a top portion of the cylindrical anchor, at least a portion of the proximal portion configured to abut a meniscus or soft tissue of the joint and to allow access into a joint space of the joint, said portion of the proximal portion including a plurality of outflow tubes that respectively connect to a predetermined pattern of openings in an outer side surface of the proximal portion (“side openings”); and
a medial portion, provided between the distal portion and the proximal portion, the medial portion having no openings provided in its outer surface,
wherein the anchor is provided with at least two internal microtubes, each having an intake in the distal portion, and each extending longitudinally through the medial portion and into the proximal portion along an axis substantially parallel to the central longitudinal axis, and each fluidly connected to one of the outflow tubes of the proximal portion, wherein an internal diameter of the outflow tubes is less than or equal to an internal diameter of the internal microtubes, and an internal diameter of the side openings is less than or equal to the internal diameter of the outflow tubes,
and wherein the internal microtubes, the side openings, and their respective sizes are together configured to utilize the natural pressure gradient that allows blood to flow in the joint to convey blood and nutrients from the cancellous bone to the meniscus or soft tissue.
